Area Forecast Discussion
National Weather Service Elko NV
246 PM PDT Tue Apr 25 2017

.SYNOPSIS...An unsettled cool and wet weather pattern will
continue across northern and central Nevada through the end of
this week. A series of upper level disturbances interacting with
Pacific moisture will produce occasional rain and snow showers
through Friday. Look for conditions to slowly improve over the
weekend.


&&

.SHORT TERM...Today through Friday.

Today through Wednesday. The brief dry period between storm system
will come to an end later today as a new storm system impacts
Nevada. This storm system will be spun up by a strong jet max that
is pressing onshore. The main fetch of moisture associated with
this system is expected to arrive late Wednesday morning and last
through Wednesday evening. This will cause showers across the
central and northern portions of Nevada. The snow levels will be
high enough that the valley should mainly receive rain. Colder
air should begin to intrude into the silver state Wednesday
evening dropping the snow levels enough for the valleys to receive
snowfall but by that time the moisture will have diminished
curtailing accumulations. A major component of this storm will be
the robust winds that will be associated with it passage. The
strongest winds will be Wednesday afternoon lasting into the early
evening and will likely see a wind advisory issued for much of the
CWA. These strong winds may cause some blowing dust and will make
travel difficult especially on north south orientated roads. Highs
in the 40s to 50s in the north and 60s to low 70s in central
Nevada. Lows are expected to be in the 30s to 40s.

Thursday through Friday. The flow will shift to north
northwesterly limiting the amount of moisture that will be able
to penetrate into Nevada. This will help to dry out the silver
state for Thursday to Friday morning leavening mostly residual
showers in the north. A small fetch of moisture should clip the
eastern portions of Nevada late Friday morning bringing some light
snow showers. There should not be much accumulations with this
snow as there will not be a lot of moisture. The winds will
continue to be gusty but not as strong as on Wednesday and will
flow from the northwest. the coldest air will arrive on Thursday
and Friday with highs in the 40s to 50s and lows in the 20s to
30s.

.LONG TERM...Friday night through next Tuesday. Models are in good
agreement Friday night into the weekend with trough energy exiting
to the southeast as high pressure builds in from off the west
coast resulting in warmer and dry conditions over NV through the
weekend and into early next week. Continued the trend of reducing
pops through the long term period, with no mention of
precipitation Friday night through Monday night. As high
pressure builds in this weekend look for temperatures to rise back
to near normal levels Saturday, with above normal afternoon highs
Sunday into early next week. Overnight lows will be below normal
Friday night and Saturday night due to fewer clouds and a
northerly flow aloft.


&&

.AVIATION...Cigs lower this evening across NW NV with rain
showers developing after midnight at KWMC. Showers will expand
south and east on Wednesday. The incoming system will have strong
jet support resulting in breezy to windy conditions across the
region, along with possibly some isolated thunderstorms over
mainly NE NV which may become an issue at KEKO. Strongest winds
are expected over western NV, with BLDU most favorable at KTPH
Wednesday afternoon and evening.




&&

.HYDROLOGY...HYDROLOGY...A cool and unsettled weather pattern
will continue through the end of this week. Some rivers and creeks
are running high and will likely see levels rise in response to
additional precipitation in the days ahead. The lower stretch of
the Humboldt River from Battle Mountain to the Humboldt/Pershing
County line is still experiencing flooding issues. At Wildhorse
Reservoir, water is being released and flowing over the spillway.
As a result, the Owyhee River is showing a rise. Outdoor
enthusiasts should watch out for and be cautious around higher
flows.

Here are the locations where flood warnings are currently in
effect:

Humboldt River - Battle Mountain: Minor flooding continues.

Humboldt River - Comus, near Winnemucca: Minor to Moderate
flooding continues.

All other monitored creeks and rivers are below minor flood stage
at this time, but will likely see rises this week due to an
occasionally wet and unsettled weather pattern. River Statements
have been issued to provide information concerning the following
sites:

Wildhorse Dam - at Wildhorse

Owyhee River - at Wildhorse

Owyhee River - near Mountain City

Bruneau River - near Rowland

Mary`s River - at Deeth
